TATE PATENT ALEXANDER F. BONDY, OF HEWLETT. NEW YORK.

SASH-LOGK. a.

Application filed August 12 1916.

To all whom it may concern:

lie it known that I, ALEXANDER F. BoNDY, a citizen of the United States, residing at Hewlett, Long Island, in the county of Nassau and State of New York, have invented a new and useful Sash-Lock, of which the following is a specification.

The device forming the subject matter of this application is a sash lock and the invention aims to provide a simple but efficient means housed within a window frame whereby both the upper and lower sashes may be unlocked simultaneously.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the crawings,

Figure 1 is a front elevation showing a window frame to which the present invention has been applied;

Fig. 2 is a perspective view showing the sash latches and the actuating mechanism therefor;

Fig. 3 is a fragmental perspective showing a portion of the lower sash;

Fig. t is a fragmental vertical section showing a portion of the means whereby the latches are actuated from a point intermediate the ends of the sill;

Fig. is a fragmental top plan of the structure shown in Fig. l.

In the drawings 1 designates a window frame including a sill 2. An upper sash 3 and a lower sash (t are mounted to slide in the frame 1. The stiles 5 of the lower sash l; are provided in their inner faces with seats 6. The stiles 7 of the upper sash 3 are equipped in their outer faces with seats like the seats 6. Bearings 8 are mounted upon and within the frame 1 and in the bearings 8 are journaled and sup-ported against endwise movement, upper shafts 9 located at both sides of the frame and housed within Specification of Letters Patent.

the frame. Secured to the shafts 9 are latches 10. The lower ends of the upper shafts 9 carry arms 11 having slots 12. Lower shafts 1% are journaled in the frame 1 at both sides thereof and are supported in bearings 15 carried by the frame. Secured to the upper ends of the shafts 1 1 are arms 16 having pins or projections 17 slidably received in the slots 12 of the arms 11 on the upper shafts 9. Angular latches 18 are secured to the shafts 14:. Attached to the lower ends of the shafts 1 1 are crank arms 19. Connections 20 which may be rigid rods are pivoted at 21 to the crank arms 19 which operate in a horizontal plane.

The inner ends of the connections 20 are pivoted at 22 to the ends of a cross arm The cross arm 23 and the connections 20 are housed within the sill 2. The cross arm 28 is secured to a horizontal shaft 2 t journaled in the front portion of the sill 2 and in a plate 26 located within the sill and carried by the rear portion of the sill. The plate has stops 27 which, cooperatin g with the end portions of the cross arm 23 limit the rotation of the shaft 24. Shaft 2a projects through the forward wall of the sill 2 and has a squared end 241 adapted to receive a key (not shown).

In practical operation, when the shaft 24; is rotated, the cross arm 23 will be swung in a vertical plane. The cross arm 23 actua-tes the connections 20, the same moving endwise. The connections 20 rotate the lower shafts 14: through the instrumentality of the crank arms 19. When the shafts 1d are rotated the latches 18 are caused to move into and out of the seats 6 in the stiles of the lower sash at, and thus the lower sash may be locked against vertical movement and may be held either in a closed position or in a partially open position.

When the shafts 1 are rotated, rotary movement is transmitted to the upper shafts 9 by means of the arms 16, the pins 17, the slots 12 and the arms 11. In this manner the latches 10 on the shafts 9 may be moved into and out of engagement with the seats in the rear or outer face of the upper sash 3, thereby to hold the said sash in a completely closed position or in a partially open one.

The arms ll and 16 and attendant parts constitute means for operatively connecting the shafts 9 and 14 for simultaneous rotation in opposite directions. the cross arm 23, the connections 20, and the crank arms 19 constitute means for simultaneously rotating the low-er shafts 1 ffroma point located between the ends of the S1112.v

What is claimed is:

1. In a device of the class described; a.

upright. shafts journaled inthe frame;- a.

latchcarr-iediby the last specified shaft and adapted to engagein the seatflof. the other sash; means for connectingtheshafts for:

simultaneous rotation; and means fen r0- I-he shaft 24;,

tating onegshaft', from as goint between the ends of the sill.

2. In a device of the class described, a frame; upper and' lower-sashes mounted to slidein the frame; shafts journaled in the fi'ame; latches carried by the shafts and coactingwith the opposed sides of the respective sashes; means for connecting the shafts fen-simultaneous notation in opposite directions; and means for rotating one shaft.

In testimony that-I claim the foregoing as my own, I have henetoc aflixedi my signature inthe presence ct two) witnesses.-
